Is it a rotated view of the wireframe plot in the example on Page 23-30? (I'm looking at the HP 48G Series User's Guide, Edition 8.) In that case, it is z = x^3 y - x y^3. But perhaps the one on the cover is not as convoluted as that one is.

I think you nailed it. I’m going to try and graph it and see what happens.
